Skin Topography Directly Measured with the Multi-Talent

The Visioscan ®  VC 20plus is a unique UVA-light video camera with high resolution to study the skin surface directly. The SELS ®  parameters (Surface Evaluation of the Living Skin) have been developed especially for this camera and are used in numerous studies. The images show the structure of the skin and the level of dryness very impressively. The camera can be used on pigmented spots and lesions and on hair. With its multi-functional software, the Visioscan ®  VC 20plus is a very flexible system to characterize skin surface condition easily, accurately and very economically. It had been used on board of the International Space Station ISS for several years.

Advantages of the Visioscan® Camera

The latest Visioscan ®  generation with improved hard- and software offer a multitude of possibilities:

  • The evaluation method SELS ®  (Surface Evaluation of the Living Skin – developed by the Institute for Experimental Dermatology, Prof. Tronnier, University of Witten-Herdecke, Germany) analyses the grey level distribution and allows the calculation of four clinical parameters to quantitatively and qualitatively describe the skin surface as an index: Skin smoothness (Se sm ), Skin roughness (Se r ), Scaliness (Se sc ), Wrinkles (Se w ).
  • SELS parameter – before treatment

SELS parameter – after treatment

  • In addition to the valuable SELS ®  calculations also other interesting parameters can be calculated: lines can be drawn on the images and the profile and the results are shown immediately. Roughness indices for up to 180 lines arranged vertically, horizontally or circularly are immediately available.
  • Special parameters have been created to describe virtually the skin topography volume (mm²) and unfolded surface in %.
  • Ageing parameters as anisotropy (directionality of the lines) and cell size (polygons between the visible lines) are at your disposal.

Aged skin, deep directional lines, less and larger polygons between the lines

  • Draw lines and free-hand objects in the picture. They can be measured accurately (e.g. length of hair after shaving, Hair thickness, pigmented spots and lesions, etc.).
  • Younger skin, lines in all directions visible, low anisotropy and more polygons between the lines

measurements of spots and lesions

  • Evaluation of desquamation (scaliness/dryness) of the skin with the foil  Corneofix ®  F 20 . A desquamation index is calculated.
  • Determination of sebum production with the foil  Sebufix ®  F 16 . The sebum production of each sebum gland can be monitored impressively in real time on the screen.

measurements of hair length and -thickness

  • Worldwide established method with a variety of interesting studies. The Visioscan ®  had been used on board of the International Space Station (ISS) to monitor the astronauts’ skin state during their stay in space.*
  • Convenient organisation of images and results in studies. Evaluate all data together by one click.
  •  Display quickly and easily "3D" images in false colour or grey values.
  •  A check calibration functions ensures the accuracy of the geometry of the camera.
  • Small, easy to handle device for all kind of applications.
  • The camera can be fitted to a tripod by its special mount.
  • Stable connection by USB directly to the computer.7The extremely economic system can easily compete with the more expensive, complex devices.
